Thanks. Due to some bad dupont cable connection the program was not entering the void loop() and not printing to the console. Was not aware about a hardware serial print. It is stable now.

@qqlapraline Just use a 5V pro mini and get rid of level converter and mosfet!
Power the 5V HC-SR04 sonar with a pro mini digital pin.
Switch on the sonar for doing a measurement and then switch off again and put the promini to sleep till the next measurement.

Thanks guys, that makes it clear for me...

@mfalkvidd Thanks for confirming about the BC message being normal protocol.
I have used the log parser (great!) and the trouble shooting flowchart (great!).
I am currently powering thru USB but as the comms problem is intermittend I need some further investigation.

How can I implement the new 2.2.0 function

#define MY_SIGNAL_REPORT_ENABLED

Should it be defined in the node and/or the gateway?
Can it be used with NRF24?
How is the RSSI value reported?
Could not find a writeup on this new function.

@mvader Thanks, got it working. Your explanation and the right indentions ( ) did it!

@mvader Thanks, have a problem translating you example to my situation

This is the card were I want to add the battery_level:

 - type: entities
        title: Levelmeter breed 
        show_header_toggle: false
        entities:
          - entity: sensor.n60breed_20_54
            name: Battery (V)
            icon: mdi:battery 
          - entity: sensor.n60breed_20_50
            name: Temperature
            icon: mdi:temperature-celsius
          - entity: sensor.n60breed_20_51
            name: Humidity
            icon: mdi:water-percent
          - entity: sensor.n60breed_20_52
            name: Bar
          - entity: sensor.n60breed_20_53
            name: Waterlevel (cm)

I played around with the following entry in configuration.yaml

sensor:
  - platform: template
    sensors:
    n60breed_20_55:
    entity_id: sensor.n60breed_20_53
    value_template: "{{ states.sensor.n60breed_20_53.attributes.battery_level }}"
    unit_of_measurement: '%'

but could not get it to work! Did not find any docs on platform Template.
Please advice

@mfalkvidd
Thanks, yes your solution could work. Also a voltage divider with a seperate child-id could work.

But my point is that the Arduino battery_level value is already available in the mysensors.json in Home Assistant.

"type": 17,
        "sketch_name": "N60Breed",
        "sketch_version": "1.0",
        "battery_level": 91,
        "protocol_version": "2.3.1",
        "heartbeat": 0

I just don't know how to get the battery_level value presented in the HA UI.

@alaskadiy No solution still.... I doubt if it has been implemented in the interface

Can anybody help my with how to display the MySensors sendBatteryLevel percentage on the HA user interface.
The percentage appears correctly in Home Assistant Developertools - States- Attrributes.
how to get this attribute displayed on the UI?

@mfalkvidd I had seen that discussion on the mysensors forum.
I my case the battery level % shows up correctly in the HA entities list attributes.
It just does not show up on the HA Console.
Have never seen it on the HA Console. What should I expect to see?

Need help on how to present Batterypct in the HA dashboard.
Is there a configuration setting needed for this?

HASSIO 0.70 on RPi with serial gateway attached still having configuration check problem with mysensors when executing

hassio ha check

This is what I did to try to solve:

• Deleted the configuration.yaml and the mysensors.json

• Restarted the RPi and hassio installed the default configuration.yaml

• Added the following mysensors configuration to the default configuration.yaml

mysensors:
  gateways:
    - device: '/dev/ttyUSB0'
      persistence_file: 'mysensors.json'
  persistence: true
  retain: true
  version: '2.2'

• Restarted the Rpi and checked that hassio had installed the mysensors.json in the /config directory
  All my sensors were added to the mysensors.json

• The whole system seems to work OK!

• However when I run "hassio ha check" on the RPi I get the following error:

core-ssh:~# hassio ha check

• There are no errors in the system log! According to the log the system is reading and writing fine to and from the mysensors.json

• The secondary annoyance from this problem is the fact that I cannot reload the configuration file after a change. The only way to reload the configuration file is by powering off/on the RPi

• I added an issue on github: https://github.com/home-assistant/hassio/issues/478

Any help appreciated

peerv created this issue in home-assistant/hassio

closed Configuration error with MySensors #478

I am now at 0.69.1 HASS on Rpi and still having configuration check problem.

This is my configuration:

mysensors:
  gateways:
    - device: '/dev/ttyUSB0'
      persistence_file: '/config/mysensors.json'
      baud_rate: 115200
  optimistic: false
  persistence: true
  retain: true
  version: '2.0'

And this is the configuration check ERROR:

core-ssh:~# hassio ha check
ERROR
starting version 3.2.4
Testing configuration at /config
Failed config
  mysensors:
    - Invalid config for [mysensors]: /config directory does not exist or is not writeable for dictionary value @ data['mysensors']['gateways'][0]['persistence_ file']. Got /config/mysensors.json'
not a valid value for dictionary value @ data['mysensors']['gateways'][0]['device'].
Got '/dev/ttyUSB0'. (See /config/configuration.yaml, line 85). Please check the docs at https://home-assistant.io/components/mysensors/

A secondary result of this error is the restarting the Rpi does NOT load a new configuration!
The only way to load a new configuration file is to power off/on the Rpi.

However all the rest seems to funtion well !?

Really need help with this.
